Environment: Journey to grok One Finite Planet.

While throughout history there have been people who realised the Earth was finite, too few have stopped to fully contemplate grok the concept. Grok that the area of the Earth is finite, that the resources of the Earth are finite, and the time the Earth will exist is finite. It was not until the 1700s that a significant number of people in different countries could even accurately picture the planet entire planet and appreciate the surface was finite, and not until the 1900s that the term 'sustainability' attracted significant attention, and people started to appreciate how resources are finite. This missing piece in this picture is still time, with most people still having a time horizon that allows time for our planet can be considered infinite, even though finite, and there is less than 2% of time remaining for life on Earth.

Environmental impact of the transition to EVs.

Its 2022, and only 1 in 8 new car purchases globally is an EV, and as only 1 in 4 car purchases is a new car, only 1 in 32, or around 3% of all car purchases, are an EV purchase. While the EV percentage is rising, there will be gas/petrol/diesel cars until at least 2045, and little reduction in emissions from the EV transition alone.

As demand for EVs will continue to outstrip supply, no one will need to choose an EV to save the planet, or run out of other choices any time soon. Bans are to pressure manufacturers to move from protecting their existing assets and produce enough EVs to meet demand, rather than force consumers into ICEVs.

Big Oil, AKA Big Fossil: How real, and what about ‘big climate’?

Yes, big oil clearly has a vested interest in arguing against climate change and downplaying risks, but on the other hand, aren’t there also vested interests exaggerating and overstating the risks of climate change? Effectively ‘big renewables’, ‘big science’ or ‘big climate’?

This is a look at the financial might on each side of the argument, and the respective motives for each side to overstate their case.

Is this really a balanced fight, or is it more like the might of ‘big tobacco’ vs ‘whistle blower medical research’ all over again?

Home Charging: The Challenge To A Green Equitable EV Transition

Moving to EVs is going to increase electricity requirements, and at a time when there is already a technical challenge to more the electricity supply to “green” source. But what it electric vehicles could solve the “green power grid” problem, provide energy security, and avert a threat of increasing inequality? It turns out dream scenario is definitely possible, but can be fully realised only if the home charging problem be solved.

1.5°C by 2026? Already +1.25°C in 2021: What You Are Not Being Told Other Than By Greta Thunberg et al., And Why Not.

I started out wondering how much temperatures have risen so far, what is the best estimate for when will reach +1.5°C , and how bad is +1.5°C anyway. I expected that finding the first two answers would be easy, but it was not. I found the answers, and why they were not easy to find.

I found that with warming at +1.0 in Paris in 2015, +1.5 logically seemed 50 years away, but in 2021 just 6 years later, we are halfway there at +1.25°C. Much changed during the Covid-19 distraction, and at this rate +1.5°C is set to be here by 2026, not the 2050 predicted at Paris.

COP26: Were The Deck Chairs Sufficiently Shuffled?

COP26. It sounds like a police officer who can’t be named. For me it raises questions such as:

  • Why “COP26” and what happened to the first 25 COPs?
  • Are all decisions are made in advance, or is anything really agreed at the conference?
  • Is there more than politicians and fossil fuel companies agreeing spin and token gestures?

Solar and Wind: Renewables alone not a substitute for fossil fuels.

At least, not alone. Solar and Wind have proven to be successful partial cost effective substitutes for fossil fuels, neither wind nor solar is stored energy. Without strategies and adding stored energy available on demand, it is impossible to reach the goal of removing reliance on fossil fuels.

Consider home solar. With solar panels you can reduce your electricity costs, but to go ‘off grid’, you need a battery or other energy storage for the solar power. Yet, the need energy storage is being installed, but not connected to the grid.

Why Hydrogen Cars are not the future, and EVs are here to stay.

After friend told me “I am not interesting in electric cars, because I will wait for hydrogen cars”, I did the research, and found that such a future would make no sense, and will never happen. It turns out that hydrogen cars were never “the ultimate”, are now worse at times or range problem, and they were only ever expensive to build and operate, higher emissions, limited interim stop gaps, for the time until we solved limitations of battery EVs.
